"The Capricorn Highway from Baralaba's cut with the Dawson River here at the moment, [with] over six metres of water over it," he said.

"We're stuck in Baralaba for a while, so people wanting to get into Baralaba at this stage, it's not on."

Goodnight Scrub isolated

About 300 people remain cut off by floodwaters at Goodnight Scrub, near Gin Gin in the Wide Bay region of south-east Queensland.

Floodwaters receded yesterday allowing some residents to cross the Perry River Bridge but levels are up again, cutting access.

An Emergency Management Queensland (EMQ) spokesman says about 100 residents were yesterday ferried across the river to Gin Gin.

Thargomindah ferry

A south-west Queensland Mayor says council is ferrying residents across a flooded river to get them on their way for Christmas holidays.

A moderate flood peak is expected today in the Bulloo River at Thargomindah where the water is currently 65 centimetres over the bridge.

Bulloo Mayor John Ferguson says the town is isolated but no properties are under threat.

"We've had to bring the mail and that sort of stuff over and some groceries, but mainly people getting out from Thargomindah to go away for their Christmas break," he said.

"We've been taking them across and letting them go.

"[It's] more a nuisance flood than anything I suppose."

Chinchilla sandbagging

Floodwaters in Charley's Creek are continuing to rise in the town of Chinchilla on southern Queensland's Darling Downs.

One family voluntarily evacuated their house while businesses on the northern side of town were sandbagged as a precaution.

Western Downs Councillor Bill McCutcheon says they were expecting the creek to peak at six metres overnight but it is only at five metres this morning.

"[It] is still below the level of the bridge which means that traffic is still open," he said.

"Our big concern at the moment is if this rain keeps up over the weekend on our already saturated catchment, we could have a major drama here over the next four days."

Creek rescue

Three people had a lucky escape when their car was swept into a flooded creek in central Queensland last night.

They tried to cross a causeway on Scrubby Creek at Gracemere near Rockhampton about 10pm (AEST).

EMQ says the group clung to trees before being rescued by a local resident.

They were not injured but their car was totally submerged.

Authorities are again pleading for people to stay out of floodwaters.

EMQ spokesman Robbie Medlin says three people have died in central Queensland this month trying to cross flooded waterways.

"One of the biggest issues that we've had recently is the amount of lives that have been lost through people entering floodwaters," he said.

"We don't want people to walk, ride or drive through any floodwaters.

"They are dangerous, we don't know how quick they're moving, we don't know what's underneath them and tragically we've seen a number of lives lost already in this wet season."

Burnett river peak

The Bundaberg Council in south-east Queensland says it has placed the region on alert as it continues to monitor flooding conditions.

The Burnett River is expected to peak at 3.5 metres in Bundaberg tomorrow morning - its highest levels in 14 years.

Disaster Management Officer Mal Churchill says that could change, as more rain falls across the region.

"Local government has moved early rather than later and put their local disaster management committee on alert, which is a standby mode so to speak to watch and monitor all the issues that are impacting on the Bundaberg area," he said.

Up to 50 council roads were cut off in the North Burnett yesterday.

There have been unofficial falls of 100mm at Langley Flats, near Monto, in the past 24 hours.

Mayor Joy Jensen says she has never seen so much rain across the region.

"It is extraordinary weather we're receiving. We can cope with the everyday weather we've had, certainly the dry times we can cope with but this is exceptional and I would say [a] one-in-100-year event," she said.

Central-west alert

Authorities are also on alert in the state's central-west with concern about possible flooding around Jericho and Alpha.

The Spirit of the Outback train was terminated at Jericho yesterday as a precaution and passengers travelled by bus into Longreach.

The Barcaldine Mayor Rob Chandler says there are no flood mitigation measures in Alpha and Jericho.

He says they will be monitoring the Bowen Downs area, the Cornish Creek and Landsborough Channels and the Jordan and Alpha Creeks.

"There are some forecasts out there for some fairly serious rain and if that eventuates, those creeks ... are all full now and running quite strongly so there is a real chance that people will be cut off or flooded in Jericho and Alpha," he said.

Brisbane tide

The Brisbane City Council is warning that minor tidal flooding is likely in river-side areas again today.

The highest tide of the month is expected to peak just before 11am (AEST).

Recent heavy rain and releases from Wivenhoe Dam, west of Brisbane, are also pushing water levels higher.

Some of the suburbs expected to be affected are Windsor, Albion, Bowen Hills, Newstead and East Brisbane.
